If the light hits the ground and is scattered then nearly all of the energy stays in the planet and eventually heats the atmosphere. If it’s reflected, even though it must pass through the atmosphere again, some of the energy is rejected back into space.

schmidtster@lemmy.world 7 months agoWhere it has to pass through the atmosphere again? With more time to heat up the atmosphere as well?
The answer isn’t this simple, I’m curious why people think they could answer it in a sentence or two.

Radiation is not absorbed by transparent gases. The ground is heated and air heats up by contact. It’s a well known fact that snow radiates back the heat and lowers the overall temperature. That’s how ice age works.

Sure, but there is more than just transparent gases, there is also some solid objects.
No that’s not a well known fact at all since it’s not even remotely correct… that has more to do with the sheer amount of ice cooling the planet than diffusion reflection.

Of course it will affect stuff: it will cool it down. It’ really very basic. Scenario 1:
Scenario 2:

And all the greenhouse gases it will heat up as it passes through them?
It’s not that simple, and you claiming it is show you have zero understanding of the potential issues. Your life age example shows that it can affect the globe at scale. Thank you for part of the answer, I’m surprised you’re still arguing after proving my point.
